Talking Point also has resources, a nice tracker for what your child should be doing at various ages as well as tips on how as a parent you can support their development:

Mabel turned 6 months old at the weekend...
She loves being tickled, likes a good fright and continues to laugh in the face of daytime sleeping (despite not coping well with being tired).
We have also just spotted that her first tooth has come through on the bottom!
Our little munchkin has been out in the world a whole half a year...where on earth has that time gone?
